Figures marked (est.) approximate the KV cache because this model's architecture details are not published. They are indicative rather than exact.
How to run openthinker locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Run this in a terminal:
ollama run openthinker:7b - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about openthinker
- How much VRAM do I need to run openthinker?
- At 4K context, the smallest published build of openthinker (Q4_K_M) needs roughly 6.6 GB of GPU memory once weights, KV cache, compute buffers and runtime overhead are counted. Bigger quantizations and longer context windows need more. It can also run partly or entirely on the CPU using system RAM, more slowly.
- Can I run openthinker without a dedicated GPU?
- Yes, but slowly. Without a GPU the model runs on the CPU using system RAM, which usually means a few tokens per second rather than dozens. You would need at least 6.6 GB of free RAM for the smallest build.
- How big is the openthinker download?
- The smallest published build is 4.4 GB. There are 12 builds in total, the largest being 61.0 GB. Leave some extra free disk space beyond the download itself.
- How do I run openthinker locally?
- Install Ollama, then run "ollama run openthinker:7b" in a terminal. The weights download on first use and an interactive session opens.
